The US military has staged bombing drills with South Korea over the Korean peninsula and near Japan in retaliation for North Korea’s latest missile test.

The US flew advanced bombers and stealth jets over the border, practising attacks by releasing live weapons at a firing range in South Korea.

Seoul's Defence Ministry said that the two B-1Bs and four F-35Bs from the US conducted drills with four South Korean F-15K fighter jets.

US and Japanese fighter jets also practised formation training over the southern island of Kyushu, according to authorities.

The show of defiance comes after Kim Jong Un flew a missile over Japan.

The regime wanted to display its displeasure at the latest round of UN sanctions, which were imposed following North Korea’s sixth nuclear test on 3 September, its most powerful to date.

Since Jong Un came to power in 2011, he has rapidly advanced the country’s nuclear capabilities, including two tests in July alone.

The regime is working towards launching an intercontinental nuclear missile that could reach the US, and many experts say achieving this goal is only a matter of time.

So far, South Korean President Moon Jae-in said he had no plan to ask the US to bring back tactical nuclear weapons to the country, despite growing pressure from conservatives.

US President Donald Trump has targeted China, which accounts for the vast majority of North Korea’s trade, in his tweets, saying the country is “trying” and “failing” to resolve the situation. He also called Jong Un “Rocket Man”.

His criticism has not been taken well by China’s Communist Party newspaper, which said pressure from the US to rein in North Korea’s weapons programs was “essentially moral kidnapping”.

China's foreign ministry also said the pressures were counterproductive and that sanctions should be imposed by the international community as a whole.

“Some related parties keep sending threatening messages both in words and deeds that include warnings of military actions to each other,” said ministry spokesman Lu Kang.

“But actually, these kinds of actions didn't help solving the problem but further complicate the situation, which do no good to the resolution of the peninsular issue.”
